Woltlab Burning Board is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. 

An attacker may leverage this issue to have arbitrary script code execute in the browser of an unsuspecting user. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Woltlab Burning Board 2.3.6 and prior versions are vulnerable to this issue.
